surge arresters are also called as lighting arresters.They
are always connected in shunt to the equipment to be
protected.They provide a low impedance path for the surge
current/surge voltage to the ground.
when the lightening ocurs,there is a voltage around some
thousands of voltage on line (35000v to 5000v) for a
fraction of second which is very high more than enough to
damage all the equioments in the grid connected to it.so
when a lightning arrester is connected then it provides a
low impedance path such that all that high voltage is
directed towards the earth resulting the protection of all
the equipments connected to the grid.

Surge means sudden increament. In electrical ckts, due to
some internal & external faults. sometimes the fault may
induce the overcurrent or overvoltage. to protect the
system from this spikes, we use the surge arresters.

Answer / mallikarjun

the surge arresters is sudeen rise in voltages or current
in line thats limit by surge arresters

Answer / mahesh sali

surge arresters is protection device protect from lighting
stroke , It help to discharge the lightning surges into the
earth by providing low resistance path , save the
electrical equipment against the Lighting

Answer / gurpreet singh

surge arrestor is the device which can only absorbs the
surges(high current) occuring due to any type of
symmetrical or unsymmetrical faults or due to lightening
strokes.it contains earthing resistors which can earth the
extra high current by providing a low resistance path.

my frnd ...

its not the limiter... it s a protective device acts as
limiter against only at faulty condition.
